Bump Testing and Calibration
RAE Systems recommends that a bump test be performed on the PGM-25XX/D prior to
each use. A bump test is defined as a brief exposure of the monitor to the calibration gas
to confirm that the sensors respond to gas and the alarms are functional and enabled.
The PGM-25XX/D multi-gas detector must be calibrated if it does not pass a bump test,
when a new sensor has been installed, or at least once every 180 days, depending on use
and sensor exposure to poisons and contaminants.
Calibration and bump test intervals are user-configurable to match national, regional, and
local regulations.
All calibration and bump test options are available under Programming
Menu/Calibration.
Each bump test or calibration option shows a countdown followed by sensor reading and
pass/fail results.
